After the idly7 secured to the framework of the Winderv thread has entered said openingV it isrei in a suitable manner. The casing 1 comtained therein by the lingers 12 and 15. The 100 section 6 of the casing 4 has an upper end wall 16 which, when in operative position, also serves to retain the running thread in the opening 11.

between two concave jaws 17 and 18 fixed to the sections 5 and 6, respectively, of the leasing 4. The active bobbin .is mounted upon a skewer 19 adapted to enter the lower portion of the bore of the bobbin. Said skewer is fixed lto an arm 20 rigidly secured to a vspindle 21 which is mounted in bearings 22 on the casing 1. Attached to the lower portionl of the spindle 21 is a stud 23 which lies within a cam slot 24 formed in a plate 25 fixed to the easing 1. A coiled spring 26 (Fig. 5) normally holds the spindle 21 in the position shown in said view. Ancarm 27 is pivoted to the casing 1 at 28 and has its rear end portion overlying the upper end of the spindle 21. Rigid with the arm 27 is an arm 29 which is arranged to be engaged by a cam bar F forming part of the traveling mechanism E.

The cam slot 24 ,is of such form that when the cam bar F acts upon the arm 29,V the spindle2l is first moved downward to Withdraw the skewer 19 from the bobbin A and the casing 4, and is then turned to swing the arm 20 and skewer 19 aside so as to be out of theway of the-bobbin A when the latter is allowed to fall from the casing 4.

The reserve bobbin B lies within a pocket 30 which is mounted upon a pivot 31. The pocket 3() is provided ,with .a bottom or support 32 and a concave seat or jaw 321 for the butt of the reserve bobbin. Said bobbin pocket 30 is notched or cut away, as shown at 33 in Figs. 4 and 6,'t'0 provide clearance for the skewer 19. K

The pocket 30 has an upper end wall 34 serving as an abutment against which the bobbin is pushed during the skewering of the bobbin. When thepocket 30 is swung to transfer the reserve bobbin to the casing -4 the edge of the end wall 34 carries the reserve thread into the flaring throatway 13, the winding tension serving to complete the movement of the thread into the guide opening 11.

'Normally the reserve bobbin pocket 30 stands in the position shown in Fig. 5 with the upper portion of the pocket resting against the cross-piece 35 ofthe casing 1, the pocket being sufficiently inclined to retain the bobbin placed therein by the operator.

The means herein shown for swinging'y the pocket 30 to carrythe bobbin to the running posit-ion comprises a cam bar G mounted on the traveling mechanism E, said cam bar being arranged to act upon acrank arm 36 which is pivoted upon the axis 28 and is rigid with a crank'arm 37. The arm 37 is connected by means of a link 38 ,with a .crank arm 39 fixed to the bobbin pocket 30.

The butt of the active bobbin is centered' 40 is a ycontractile spring acting on the arm 37 to return the reserve bobbin pocket to normal position after the passage of the cam bar G On the upper end of the rock shaft 7 is a crank arm 41'which is arranged to be engaged by a cam har or flange H on the traveling mechanism E. Y

0n the casing section 6 is a 'flange 42. When the section 6 is in closed position, the flange 42 partly closes thespace between said section and the bottom 32. XVhen the operator drops a bobbin into the pocket 30, the flange 42 prevents the bobbin from entering said space. If the butt of the bobbin should rest upon said flange, the section 6l will pushthe bobbin onto the bottom 32 when the section 6 is swung open.

Assuming the parts to bein the position shown in Fig. 5 the operation is as follows:r

By the time the traveling mechanism E reaches the bobbin holder, the bobbin A will have been completely unwound or the thread `will have broken, but if the thread is still running, the mechanism' E will break they thread. In the travel of the mechanism E the cam bar F engages the arm `29and causes the skewer 19 to be withdrawn from the bobbin A and swung aside." lf the skewer should tend to stick in the bobbin, the latter is held by the jaws 17 and 18 during the withdrawal of the skewer. The dwell portion F of the cam bar F holds the skewer in the withdrawn position for the necessary length of time. The cam bar `or flange H then engages the crank arm 41 and causes the 'section 6 of the casing 4 to be swung into the position shown in Fig. 6, where' upon the spentbobbin drops out of the casing'4, the bobbin beingreceived upon a conveyor I (Fig. l) or otherwise disposed of. The dwell portion ofthe cam flange H holds the pivoted section 6 in the-position `shown in Fig. 6 for the ytime being.` The cam bar G' of the traveling mechanism then engages the arm 36 and causes the pocket 30 to swing rearwardly into they position shown in Fig. 6, thus placing the reserve bobbin B in the fixed portion 5 of the casing 4. The butt of the bobbin B then stands between the jaws 17 and 32L and is thus centered for the entry .of the skewer. The dwell portion G of' the cam' bar G yholdsthe bobbin pocket 30 in this position until the cam bar F has left the arm 29 and allowed the spring 26 to move the skewer 19 into engagement with the bobbin B. 4In the continuing'travel of the mechanism vE the cam bar Gr leaves the crank arm 36,.whereupon the spring 40 restores the pocket 3() to normal position. The cam flange H then leaves theorank arm 41, whereupon the torsion spring 9 swings the section 6 of the casing 4 into closed posit-ion. K

While the travelingy mechanism E is passmechanism has passed the bobbin-holder the operator drops a reserve bobbin into the space between the walls 2 and 3, the bobbin coming to rest in the pocket 30, andputs the end of the reserve thread in the clamp The bobbins shown in Fig. 5 are ordinary Warp bo'bbins having Warp-wound yarn masses thereon. It has been found that a higher winding speed can be attained with warp-Wound bobbins than with tillimg-vvound bobbins, as at the higher speeds the layers of lling-Wound yarn tend to slough off. The present invention, however, is not limited to any particular type of yarn mass.

lVhile the present embodiment of the invention hasbeen described in considerable detail such description has been given for the purpose of affording a. clear understanding of the construction and mode of operation of the form of bobbin-holder and bobbin-holder-operating devices herein illustrated and not for the purpose of dening the invention. As indicated by the scope ot' the appended claims, the invention is susceptible of embodiment in widely different forms.
